Luna-Grabber | The best discord token grabber made in python | Chat library

I am making a chat app where 10 messages are loaded per page. The messages are sorted from oldest to latest, so the new messages come in bottom and old messages are in top. I tried to use skip() and limit() methods it didnt work.

I'm working on a Testproject, where I want to exchange information via peer-to-peer from one Mobile device to another.

My goal is to make a little chat widget, where when you post a message, you can see it on all devices, which are connected, a bit like this: So if I have one Mobile device, where I send the message, it's seen by all devices.

The reason why I'm asking for help here, is because I've looked around and found two options for peer-to-peer in Flutter: A faulty example of a peer-to-peer connection in Flutter, with practically no documentation

A better-documented example of peer-to-peer connection in Flutter, which also doesn't seem to work.

According to some people, the first option doesn't even work anymore. I've tried both and neither of them managed to achieve what I wanted. It's possible that I don't understand the difference between them 100%.

With this I don't even know really, how to write the Dart/Flutter code, to test the connection between two devices.

I have experience with using Sockets and socketstreams on Java, where one device would send something into the socket stream and the other read it out of the socket stream, but there one device was server and one client.

It would really help me if you could write a simple model, where this peer-to-peer connection works. Because the "documentation" available isn't helping me at all.

Here is the non functioning code, which I have so far

I followed a tutorial and was able to copy/build a simple real time web app. I understand everything from the code except for one thing. The 'disconnect' event. I removed most of the code for simplification, but it goes like this:

What is the best practice to handle seen/unseen messages in a chat room application based on Nodejs/SocketIO/React.

Consider User1 sends a message to a room. If another user has seen that message, notify all users that the state of message has been seen.

In my opinion using message brokers can be the better solution instead socket. I actually think that socket should only handle chat messages that are synchronously. but for seen/unseen status I prefer message brokers that are asynchronous. Are there any solutions or best practice in large scale applications?

Hi i'm building a chat app with angular for a school project i'm using firebase for my backend and i have an issue with my ngfor.

For exemple if i reload the page i will see nothing unless i hover my routerlink on my navbar. However sometime it will work after some time on the page without any action

When i recieve message i need to be on the page to see them ...

When i reload my page in first time my array is empty this may be what makes the ngfor bug array on reload.

I'm using ngOnInit() to subscribe :

I created a messenger using Python Socket, when I use two clients, for example, when one user leaves the chat, the second user can send 1-2 more messages and after that the server stops accepting messages from other users, that is there is a well-known error Broken pipe 32. I understand the terminology of the error, perhaps the error lies on my server in a While True loop (a loop that includes all the actions that users carry out among themselves), because there is a fabulous code in the form:

I need some help with Firestore building a chat app. I've looked at the documentation but I couldn't find the answer I need.

I'm building a real-time chat (many-to-many) that must handle thousands of messages, and those messages can also be edited, deleted and undeleted. The main problem is that loading all the messages once (as Firebase suggests) and then manage them on the FrontEnd side freezes my frontend application for the huge amount of messages. I tried to do that with the pagination API but I got some edge cases e.g.

How do I force the server to receive messages from the client and display the message: "{name} send message: {data}"? For example, a user sends a message to another user, and when a user named John sends the message "Hello Alice, how are you?", The server will be displayed at this point - John will send a message: Hello Alice, how are you? I will be grateful for your help. I hope will find the answer to this question in this article. Code below:

server:

below is my code in flutter, when I send a message all the timestamps for every message update to the current time, how do I ensure the times don't change on any old messages? I have pulled the timestamp out correctly just missing what I am doing wrong to save the individual time stamp. I am not using a firebase timestamp just using what dart gives me for DateTime
